Penstemons are bee-friendly, slug-resistant perennials. We pick 10 of the best.
Penstemons are gorgeous, bushy perennials, highly valued for their long season of flowers in a range of colours.
They can be short-lived, so it’s a good idea to take softwood cuttings from them in summer – it’s quick, easy and will reward you with lots of new plants for free.
